[patch] [SCSI] mvumi: use GFP_ATOMIC under spin lock

[Dan Carpenter]

This is called from the interrupt handler and with spin_locks held.  Use
GFP_ATOMIC.  The call tree looks like:
  mvumi_isr_handler() <- takes a spin lock
  -> mvumi_handshake()
     -> mvumi_init_data()
        -> mvumi_alloc_mem_resource() <- GFP_KERNEL
